First i would thank my friend Xavier Picamal for remind me in this way, another way to crack oracle password yo could consider it the fastest way to crack oracle password.
SQL> SELECT dbms_metadata.get_ddl(‘USER’,’TEST’) from dual ;
DBMS_METADATA.GET_DDL(‘USER’,’TEST’)
——————————————————————————–CREATE USER “TEST” IDENTIFIED BY VALUES ‘1E1A7CDA2ED2730E’
DEFAULT TA
SQL> conn / as sysdba
Connected.
SQL> alter user Test identified by Test_123 ;
User altered.
SQL> conn test/test_123
Connected.
SQL> alter user Test identified by VALUES ‘1E1A7CDA2ED2730E’
2 ;User altered.
SQL>
SQL>
SQL> conn Test/test;
Connected.

Or you could use Hash Value and use another software to cracks Such as : soonerorlater , Online Crack Website.
